SELF-FEEDIN G AND POWER PULL-BACK HAY-PRESS.

Specification of Letters Patent.

Patented Sept. 17, 1907.

Application filed May 26, 1906. Serial No. 318,870.

To all whom it may concern:

Be it known that I, Gnonen SCHUBERT, a citizen of the United States,residing at Fort Worth, in the county of Tarrant, and State of Texas,have invented a new and useful Self-Feeding and Power Pull-Back Hay-Press, of which the following is a specification.

My present invention refers to a self-feeding and power pull back haypress: and refers to hay presses having a cross head pivoted on near thefree end of the extension beam with depending rollers on said crosshead, to engage with cams formed on arms pivoted within the field of therollers. And my invention consists: in pivoting levers or bars on theextension beam, and operating such bars by one of such armssimultaneously and separately; to pull the plunger back, and to alsooperate the self feeder. And also simplifying such self feeder,

In the drawings; Figure 1 is a top plan view of the extension beam andmy improved mechanism, and a portion of the hopper and self feeder. Fig.2 is a side view of said mechanism. Fig. 3 is an edge or side view of abar with a roller and guard thereon. Fig. 4 is a view similar to Fig. 1,showing the mechanism in different position. Fig. 5 and 6 are plan andedge views of a catch to engage and disengage with a roller. Fig. 7 is alongitudinal section view of the controlling wing of the hopper, takenon line 11, of Fig. 4, looking as indicated by arrow, showing a planview of the advance arm and its mechanism. Fig. 8 is a detail plan Viewof a crank arm used on the shaft of the controlling wing. Fig. 9 is across section on line 22, of Fig. 1, looking in direction of arrow,showing the location of the bars on the extension beam. Fig. 10 is aside view of the press, on a slightly reduced scale, and with thenonimportant parts of the body of the press and side wing of the hopperprinciple broken away to show parts beyond in full lines, and toeconomize space, and Fig. 11 is an opposite side view of the hopper,with part of the operating wing partly broken away, to show parts beyondin full lines. f

Referring to Figs. 1 and 2; 1, 1 represents the side plates, and 1 thebottom plate, all secured in position by the corner bars 2 2, formingthe bale chamber, 1.

2, 2 represents the angle bars forming the extension beam, 2 united attheir front end; (the power end of the press is considered the frontend) and withtheir inner ends connected to the projecting ends ofthecorner bars 2 2, all arranged as in common use.

3 represents the usual casting on the front end of the extension beam,provided with the usual perforations to receive the boss or pivot of thecross head 4, and arms 5 and (l. The arm 6 is pivoted on the outer endof the casting 3, and within the field of the rollers 4 4, and providedwith a cam 6 extending upward into the path of the rollers 4 4, andprovided with a nose, 6" on its free end, to engage the end of theplunger bar 17. The arm 5 is pivoted on near the inner end of saidcasting and within the field of the rollers 4 4, and provided with a cam5 projecting within the field of said rollers 4 4, and provided with astraight face, 4 of a specifled length, later on noted.

7 represents a bar, (see Figs. 4 and 9,) pivoted on the far angle of theextension beam, and shiftably in a slot 8 formed by a bar 8, blocked upto clear the bar 7, and secured on said extension beam in such position.

9 is a bar or rod, (see, Fig. 3,) pivoted with its fiattened end on theprojecting bar 7, and with its opposite end rounded and supportedshiftable in an eyebolt 5 carried by the free end of the arm 5.

10 represents a collar adjustable on the rod'9, on the front side of theeye bolt 5.

11 is a bar or link, pivoted on lugs 10 of the collar, 10, and with itsopposite end pivoted to two links, 12, 12 in turn pivoted to the end ofthe rod 9. i

13 is a spring coiled on the center pivot of the links 11 and 12, 12,and with its ends secured to the end pivots of said links, in a mannerto hold' said center pivot against the rod 9. 1

14 is a roller on the rod 9, a short distance from its rear or pivotedend, with a brace 15 extending from the upper end of the roller 14 toand beyond the pivot of said rod.

16 is a rod pivoted on the bar 7 and extending through below the plungerbar 17 to the opposite side and body part of the press, and through aneye bolt 41-, later on noted.

18 represents a second bar, pivoted on a bracket 19, rigid on the farside of the extension beam, and rest ing on the bar 8 and projectingbeyond said bar 8, and connected by one or more links or rods 20, 20, tothe plunger bar 17.

21 represents a catch, (see Figs. 5 and 6,) pivoted on the bar18, on theouter side of the bar 8, with the hook 22 in position to engage with theroller 14; and having shoulders 23 and 24, depressed, to engage with thefront side or edge of the bar 18, and with its rear end turned down toengage with the edge of the bar8. The rear end of the bar 8 is turnedin, and the shoulder 23 of proper length to bring the hook 22 directlyover the roller 14, as indicated in Fig. 4, when both bars 7 and 18 areshifted back.

25 is a bar rigid on the bar 18, a short distance from latters pivot,and projecting rearward and outward, (see Figs. 1 and 8,) and with itsend curved upward to engage the plunger bar 17, and braced in positionby the brace 27 extending from said curved end to the pivot of the bar18.

27 is a side stop for the plunger bar 17.

Referring now to the self feeding part of the press. 28 represents theend or controlling wing'i) per, (see Figs. 1, 2, and 10,) said wing isrigid on the shaft 29, which is pivoted in perforations formed in thefront and upper corners of the side plates 1, 1.. 30 and 31 are crankarms rigid on the projecting ends of said shaft.

29, 32, 32 are side wings,hinged to the plates 1, l, by any commonhinges 33, 33.

34, 34, are brackets rigid on the side plates 1, 1, located a shortdistance back of the shaft 29, (see Figs. 1, 4, and 11.) 35, 35, arelevers centrally pivoted on said brackets 34, 34, and connected withtheir rear ends by eye bolts 35, 35 and links 36, 36 to brackets 32, 32rigid on the wings 32, 32, said levers having their free ends curved tocoincide with the path of rollers 37 37 on the crank arms 30 and 31. 39,39 are spurs above the inner end of said curves, on said levers.

30 and 31 are spurs on the crank arms 30 and 31 projecting forward andupward, (see Figs. 2 and 8,) and connected to. the end wing 28 by bars40 and 40, and the roller 37, on the opposite end of said crank arm 30in contact with the lever 35. The crank arm 31 has a similar roller 37in contact With the lever 35 on the opposite side of the press; andprojecting with its body beyond the said roller 37 and bracket 34, andset down, (see Fig. 8,) to clear said bracket 34; and having pivoted inits end an eye bolt 41, to support shiftable the rear end of the rod 16.42 is a spring on the rear end of said rod 16 resting with one endagainst a pin 43 near the end of said rod, and with its opposite endagainst the eye bolt 41. 1 I

45 is a downwardly projecting spur on the crank arm 31, a short distancefrom the shaft 29.

46 is a bell-crank lever, (see Figs. 7 and 10,) pivoted with its heel onnear the end of the spur 31 and projecting with its longer end downwardand having pivoted thereto a bar 47, extending through a perforation ofthe spur 45, and with its end in position to be engaged by a pin 44 inthe rod 16, located on the front side of the eye bolt 41.

48 represents an advance arm or tongue, (see Figs. 7 and 10,) pivoted onthe wing 28 near the shaft 29, finding its bearings in the flange of thewing 28 and in a block 49, and projecting with its body through a slotformed in the wing 28, and pressed downward by a spring 51 on the heelof said tongue 48, and resting with its opposite end on the shaft 29.

52 represents a dog pivoted between the wing 28 and the brace 40, andwith its body in position to engage the tongue 48, and pressed in tosuch engagement by a spring 53 secured to near the end of said dog 52and to the bearing 49. 54 is a bar connecting said dog 52 to the bellcrank lever 46.

55 are bridle bars secured to the plates l, 1 and projecting forward,and with their ends united by a cross bar 56, extending across above theplunger bar, 17 a short distance from the front end of the plates 1, 1,and braced by stay bolts 57, extending from said cross bar 56 to theextension beam.

58 represents the usual plunger rigid on the plunger bar 17.

59 represents a spiral spring anchored with one end on the spur 31 andwith its other end on a bracket 60 rigid on the cross bar 56.

In operating the press: the cross head is rotated in the direction ofarrow in Fig. 1; and as one of the rollers 4 leaves the plunger bar 17it moves against the cam 5 and moves the arm 5 in the direction ofarrow, from the position seen in dotted lines in Fig. 4, and thus movethe rod 16 and the bar 7 in the same direction, and the hook 22extending over the roller 14 will in turn be moved in the samedirection, and in turn move the bar 18. By the time the arm 5 and itsconnecting mechanism is shifted to the position as seen in Fig. 1, theplunger will have been drawn out or back, and. the shoulder 24 engagingthe side of the bar 18 will cause the pivoted catch 21 to become rigidon the bar 18, and cause the hook 22 to shift off the roller 14; by

reason of the pivots of the bars 7 and 18 being in dif- V ferent fields,and thus release said bar 18, which will now begin to be drawn back asthe plunger moves in. As the bar 18 is moved from the position seen inFig. 4 to the position seen in Fig. 1, the far and curved end of the bar25 will move against the plunger bar 17 and crowd or shift said plungerbar 17 over against the arm 6, or within easy reach of said arm 6. Andthe bar 7 continuing on its forward movement until in the position seenin full lines in Fig. 4 where it will be retained until the roller 4shall have passed beyond the face 4 of the cam 5 after this the spring59 will open the hopper, (as later on noted,) and thus draw said arm 5and its mechanism back to the position seen in dotted lines in Fig. 4',again bringing the roller 14 be neath the hook or latch 21. As the arm 5moves forward as described, and the rod 16 being pivoted in the free endof the bar 7, said rod also moves forward, and first compressing thespring 42;by reason of the pressure of the rod 16 on the eye bolt 41being nearly online with the pivot of the shaft 29, and the resistanceof the spring 59 and the weight of the wings 32, 32. As the spring isthus being compressed, the rod 16 moves forward, the pin 44 will moveagainst the end of the bar 47 shifting it in said direction, and by themeans of the bar 54 and bell crank lever 46 will withdraw the dog 52from beneath the tongue 48 and thus allow said tongue 48 to move down onthe hay. The crank arms 31 and 31 now begin to move forward, moving thelevers 35, 35 from the position seen in Fig. 10 to the position seen inFig. 2, thus closing the side wings 32, 32 of the hopper, and thecontrolling wing 28 will also have moved from the position seen in Fig.10 to the position seen in Fig. 2, by this time the arm 5 and itsconnected parts will have moved to the position seen in Fig. 1. And theplunger now having been withdrawn, and the rod 16 continuing on itsforward movement far enough to close the controlling wing 28 down to thelevel of the upper edge of the plunger and retained there until theroller 4 has traveled past the straight face 4 after the wing 28 willopen out as previously described; and the rollers 37 37 coming incontact with the spurs 39, 39 will open out the side wings 32, 32. Afterthe controlling wing 28 has been depressed or closed down, and theplunger moving in the bale chamber 1 will move against the downwardprojecting portion of the tongue 48, and pressing said tongue back or upagainst said wing 28 and admit of the dog 52 to engage said tongue 48and lock it to said wing 28 again. The rear end of the guard 15 extendsfar enough down to always shift beneath the clutch 21 and the bar 18. Ifthere is an excessive charge on the hopper such as the feeder cannothandle, or the plunger is wedged extra solid, then more pressure on thecollar 15 will cause the spring 13 to yield and allow the central pivotof the links 11 and 12 to open out and allow the collar 10 to shift ontherod 9 andthe links assume the position seen in Fig. 3, allowing therod 9 to shift in the eye bolt 5 and the team to pass on Withoutstraining the said parts. After the pressure on the collar 10 has beenreleased the spring 13 will shift the links 11 and 12 to their originalposition. I
